You can sell consignment and share any sales with your artists using Transparent Kitty. Nice way to easily do it. You would still have to setup their "stuff". With the templates you could easily give each Artist a nice look all their own too.

I too was running a consignment model on Shopify, and couldn't find a way to make it work. So I decided to build a product that does just that.

The goal was to build a new and modern consignment software that allows business to decrease cost with tools that saves them time, and increase revenue by making it easier to connect to more sales channels (like Shopify).
